Step 1520-7

1. Turn the power off.

2. Unplug the system unit power cable from the wall outlet.

3. Record the slot numbers of all the ISA and PCI adapters. Label and record the

location of any cables attached to the adapters. Remove all the adapters.

4. Remove all the memory modules.

5. Remove the CPU card.

6. Unplug the power cables from all the SCSI devices.

7. Unplug all the fans, except the fan in the power supply.

8. Connect the system unit power cable to the wall outlet.

9. Turn the power on.

Does the fan in the power supply turn on and the power good LED come on
and stay on?

Replace the system board. Go to "Map 0410: Repair Checkout" in the
IBM RS/6000 Diagnostic Information for Multiple Bus Systems.
